TILE.

Specification of Letters Patent.

Patented Dec. 10, 1907.

Application filed Fe ru ry 11, 1907. Serial No. 356,771.

To all whom it may concern:

Be it known that I, PATRICK JOSEPH Mo- GUIRE, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, county and State of New York,

have invented a new and Improved Tile, of which the following is a full, clear, and exact description.

The invention has in view the provision of a tile or the like wherein a permanent fastening of the same is insured when set; also to provide for the shielding of the tile from the moisture of the cement used to hold it in place, whereby theglazed face of the tile will not craze by reason of the unequal expansion and contraction ordinarily caused by said moisture. i

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a rear elevation of a tile embodying my invention; Fig. 2 is a longitudinal section of the same substantially on the line 2 2 of Fig. 1; and Fig. 3- is a cross section on the line 33 of Fig. 1.

In carrying out my invention I employ a tile 1 ordinarily having the usual glazed front face, or other building slab, of any desired conformation or color. The rear face of the tile is rabbeted at opposite edges forming this side of the tile of somewhat narrower width than the front face, said rabbeted edges being undercut to provide guide-grooves 2, as best shown in Fig. 3. The guide-grooves 2 are designed to receive the inturned edges of a backing-plate 3, which is preferably constructed of sheet metal, with slots 4 or other perforations cut in the face thereof, as shown in Fig. 1. The backing-plate 3 is of such extent as to practically cover the entire rear face of the tile, leaving only suflicient clearance at the edges, as represented in Fig. 1, in order that the backing-plate of the next adj acent tile will not contact therewith when the tiles are set in position.

As best shown in Figs. 2 and 3, the rear face of the tile is covered with a coating 5 of para'flin, shellac, or other suitable waterproof material.

Seated on the coating 5 and pressing at opposite sides on the under face of the back ing-plate 3, when the latter is in position, is a curved spring plate 6, also preferably constructed of sheet metal and serving the double function of bindingly holding the backing-plate in place and acting as a shield to prevent the direct contact of the cement used in setting the tile, with the coating 5. By this construction it is possible to keep the moisture of the cement from soaking into the tile which is ordinarily the cause of the crazing of the glazed face of the latter, due to the unequal expansion and contraction.

In the use of the tile, it is applied to the floor, wall or other part of the building in the ordinary manner, the cement passing through the slots or perforations 4 in the backingplate and acting to securely key the tile in place when the cement has set, thus insuring a permanent fastening not attained in the ordinary tile construction.

It is obvious that various immaterial changes may be made in the tile from that shown and described, Without departing from the nature of my invention; and I consider that I am entitled to such modifications as fall within the scope of the annexed claims.

Having thus described my invention I claim as new and desire to secure by Letters Patent:

1. A tile having its rear face provided with rabbeted opposite edges with undercut grooves formed therein, an independent er forated backing-plate for said tile slidab e in said. grooves, and means interposed between said plate and the rear face of the tile for holding the plate in position.

2. A tile provided with guide grooves at opposite edges, a perforated backing-plate slidable in said grooves, a waterproof coating covering the rear face of the tile, and a curved spring plate acting as a shield interposed between said coating and the backing-plate for holding the backing-plate in position.

3. A tile provided with guide grooves at opposite edges, a perforated backing plate slidable in said. grooves, and a water-proof material coated on the back of the tile covered by said plate.

' 1. A block, tile or like body having a perforated plate spaced from and covering the rear face thereof, said plate being confined within the outline of the body whereby when a plurality of such tiles are set on a bed of cement or the like, their edges may be placed close together and. the cement will enter the Y 5. A block, tile or like body having a perforated plate covering the rear face thereof, said plate being of slightly less extent than the rear face of the body and separated therefrom to provide a space therebetween, whereby when a plurality of such tiles are set on a bed of cement or the like, their edges may be placed close together and the cement will enter the perforations of each plate and thus securely bind each tile in place.

6. A block, tile or like body having a perforated plate covering the rear face thereof, with the sides of the tile projecting beyond the edges of said plate, whereby when a plurality of such tiles are set on a backing of cement or the like, their edges may be placed in substantial contact, and a shield interposed between the plate and body for holding the plate in position.

7. A block, tile or like body having a perforated plate covering the rear face thereof,

-said plate being confined within the outline of the body whereby a lurality of such tiles, when laid, may have their edges in substantial contact, and a spring shield interposed between the plate and tile for holding the plate in position.

8. A block, tile or like body having a perforated plate slidably attached to and covering the rear face thereof, said plate being slightly separated from said rear face, whereby a space is provided therebetween, said plate being also confined within the outline of said body, for the purpose described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

PATRICK JOSEPH MoGUIRE.
